Increasing the video size of a Yahoo Messenger webcam conversation allows you to see your friends more clearly and in higher resolutions. This is especially beneficial if you and your friend are using high-quality webcams that support high-definition video. A Yahoo Messenger webcam conversation allows you to share live video while instant messaging or using the voice call feature. As long as your friend is online, you can start a video call at anytime and increase the video size for optimal image quality.

Right-click the online contact you want to start a webcam conversation with from the Messenger list, then click "Invite to View My Webcam," "View My Webcam," or "Start Voice Conversation" to start a webcam conversation.

Click the "Messenger" tab in the upper-left corner and click "Preferences" to bring up the Yahoo Messenger Preferences.

Click the "Webcam" tab and select the "Large" image size option to increase the size of the viewing window.
